Embodiment approach 1

[0061] figure 1 It is a block diagram showing the functional configuration of the image processing apparatus 10 according to the first embodiment. The image processing device 10 generates depth data of the first image using a first image and a second image (for example, a stereo image) taken from different viewpoints. The first image and the second image are, for example, stereo images (an image for the left eye and an image for the right eye).

[0062] Such as figure 1 As shown, the image processing device 10 according to this embodiment includes a parallax value calculation unit 11, a segmentation unit 12, and a depth data generation unit 13.

[0063] The parallax value calculation unit 11 detects the corresponding pixel in the second image for each representative pixel in the first image, and thereby calculates the parallax value between the representative pixel and the corresponding pixel. That is, the parallax value calculation unit 11 calculates a parallax value for some pix...

Embodiment approach 2

[0083] Next, Embodiment 2 will be described with reference to the drawings.

[0084] Figure 4 It is a block diagram showing the functional configuration of the image processing apparatus 20 according to the second embodiment. The image processing device 20 according to this embodiment includes a feature point calculation unit 21, an alignment processing unit 22, a parallax value calculation unit 23, a segmentation unit 24, a segment combination unit 25, a depth data generation unit 26, and an image processing unit 27.

[0085] The feature point calculation unit 21 calculates feature points of the first image as representative pixels. Specifically, the feature point calculation unit 21 calculates feature points using the feature amount extracted by the feature amount extraction method. As the feature extraction method, for example, it can be used in Reference 1 (David G. Lowe, "Distinctive image features from scale-invariant keypoints", International Journal of Computer Vision, 6...

Abstract

An image processing device (10) generating depth data using a first image and a second image captured from mutually different viewpoints, comprising: a parallax value calculation unit (11) for multiple For each of the representative pixels, the disparity value of the representative pixel is calculated based on the positional relationship between the representative pixel and the pixel in the second image corresponding to the representative pixel; the segmentation part (12), based on the similarity of the pixel value, will The first image is divided into a plurality of segments; and the depth data generation unit (13) determines, for each segment, a parallax value of the segment based on a parallax value of a representative pixel included in the segment, thereby generating a depth corresponding to each segment. depth data.

Description

Technical field [0001] The present invention relates to an image processing device, an imaging device, and an image processing method that generate depth data using a first image and a second image taken from different viewpoints. Background technique [0002] In recent years, 3D displays that display 3D images have become widespread. In addition, the demand for 3D cameras that capture 3D images displayed on such 3D displays has also increased. In a normal 3D camera, two sets of lenses and sensors are used to take stereo images. [0003] There is known a method of generating depth data representing the depth of the stereoscopic image using a stereoscopic image captured by such a 3D camera. For example, by detecting corresponding points for each pixel in a stereo image, and calculating the parallax value between the corresponding points, depth data can be generated. In addition, the depth data generated in this way can be used to perform various processing on the stereoscopic ima...
